Final answer:

Frictional force on sandpaper vs. glass surfaces explained.


Explanation:

Frictional force is the force that makes it more difficult to push a block of wood on a sandpaper surface than on a glass surface. Frictional force is the resistance that objects experience when moving against each other due to the roughness of the surfaces involved.

On a sandpaper surface, there is more frictional force acting against the motion of the block compared to a smooth glass surface. The rough texture of sandpaper increases the contact area between the block and the surface, resulting in a stronger resistance to motion.
